Abstract
A method controls the slip value of a wheel of a vehicle, wherein: a controller is used which outputs a manipulated or correcting variable on the basis of a determined control deviation; the control deviation includes a slip-based component and a rotational-speed-based component; in the case of the slip-based component, the target slip is offset against the actual slip; in the case of the rotational-speed-based component, the slip-based component is offset against a normalization variable dependent on the vehicle speed; and the slip-based component and the rotational-speed-based component are weighted according to slip for the determination of the manipulated or corrected variable.

A method for controlling a slip value, the method comprising:
- outputting, via a controller, a correcting variable for the slip value of a wheel of a vehicle based on an identified control deviation,
- wherein the control deviation comprises a slip-based component and a rotational speed-based component,
- wherein, in the case of the slip-based component, a target slip is offset against actual slip,
- wherein, in the case of the rotational speed-based component, the slip-based component is offset against a normalizing variable dependent on vehicle speed, and
- wherein the slip-based component and the rotational speed-based component are weighted depending on slip in order to determine the correcting variable.
A control unit for a vehicle, comprising:
- a calculating unit which is parameterized and/or designed to carry out acts of:
- outputting a correcting variable for the slip value for a wheel of a vehicle based on an identified control deviation,
- wherein the control deviation comprises a slip-based component and a rotational speed-based component,
- wherein, in the case of the slip-based component, a target slip is offset against actual slip,
- wherein, in the case of the rotational speed-based component, the slip-based component is offset against a normalizing variable dependent on vehicle speed, and
- wherein the slip-based component and the rotational speed-based component are weighted depending on slip in order to determine the correcting variable.
